Pipeline integrity and ground movement hazards

输送管道是自然资源行业的关键要素，用于将液态烃和天然气产品从油田开发区域安全高效地输送到国内和国际市场。这些管道系统可以延伸数百公里，跨越各种操作、环境和岩土特征的地形。对于包括生产商、管道运营商、监管机构和公众在内的行业利益相关者来说，重要的问题是在管道生命周期内建立一个安全可靠的运输系统。长期不同的地面运动事件对埋地管道施加岩土荷载，可能引发管道变形机制，并超出有关可使用性或最终极限状态的管理设计验收标准。这种地质灾害对管道运输系统的设计、施工、运营和维护提出了工程挑战。该研究项目的主要目标是开发合理的工程指南和评估工具，以量化和评估各种设计条件下长期差异地面运动事件对埋地管道系统的影响。在此基础上，可以制定有效的设计程序和干预政策，以确保管道的完整性并符合法规要求。

Transmission pipelines are critical elements of the natural resource industry for the safe and efficient transportation of liquid hydrocarbon and natural gas products from field development areas to domestic and international markets. These pipeline systems can extend for hundreds of kilometers in length over terrain with varied operational, environmental and geotechnical characteristics. For industry stakeholders that include the producers, pipeline operators, regulatory agencies and public, the significant issue is establishing a safe and reliable transportation system throughout the pipeline life cycle. Long term differential ground movement events impose geotechnical loads on buried pipelines that may initiate pipeline deformation mechanisms and exceed governing design acceptance criteria with respect to serviceability or ultimate limit states. This geohazard represents an engineering challenge for the design, construction, operation and maintenance of pipeline transportation systems. The primary goal of the research program is the development of rational engineering guidelines and assessment tools that can quantify and evaluate the effects of long term differential ground movement events on buried pipeline systems for a range of design conditions. On this basis, effective design procedures and intervention policies can be developed to ensure pipeline integrity and demonstrate regulatory compliance.
